In some cases, the CLANG38 toolchain profile in LTO mode emits GOT based relocations in spite of our attempts to avoid this, by using hidden visibility, -Bsymbolic etc. On AARCH64, we managed to work around this by processing the GOT based relocations in GenFw. As it turns out, the same issue exists on 32-bit ARM, but unfortunately, we cannot use a similar trick to get rid of the GOT entry, and the relocation metadata is insufficient to locate the GOT entry in the binary. Note that in this particular case, we are interested in PIE linking only (i.e., producing a .rela section containing dynamic relocations that the startup code can process directly), and not in position independent code generation, and by passing the -pie option to the linker directly using -Wl,-pie (and dropping -shared), we can coerce the GOLD linker into doing only the former rather than both when it performs its LTO code generation.
